> This is one of the "most wanted" hacks to do. Long time ago I tried it without success, but now I finally founded and alternative. Following the same principle of MYFACES-3287, we can use a "find component expression" to locate the composite component later and setup the environment correctly. As with MYFACES-3287 if the component is inside a datatable, the code on the listener will only execute once, and not per row, which is something expected and the affected properties on the component has the same limitations. 
> The other part of the hack include use a listener to PostAddToViewEvent to subscribe the listener after the tree is built, so we can calculate the "find component expression" correctly.
